I don't know the answer to the question on whether this is general anxiety or obsessive, but wanted to let you know I have similar thoughts. My husband travels a lot and if I don't hear from him often I immediately think he's dead. I know it is irrational, but that's what my mind does. I haven't told my therapist about this, but I'm going to at my next appointment.

Also - I saw you wrote you are supposed to start taking Lexapro. My doctor prescribed that to me, but I haven't started yet. I'm resiting taking meds, but not sure why. I'll be interested to hear if it helps you
